Re: [TCML] SRSG vs. RQSG (Sucker Gaps)

[Brandon Hendershot <brandonhendershot@xxxxxxxxx>]

Hi Gary,

Good to know. It seems to me that coils with RSG's of that type sound
better,
at least according to YouTube. But I'll be satisfied knowing that if I
didn't go
with a propeller type gap, it would've been more trouble than necessary. I
guess I ought to go study up on RSG's now... Thanks Gary!
